I dropped my Blackberry Curve 9360 head first into coffee by accident - I immediately turned it off and stripped it to dry. After putting it together, everything was cool and working normally and then after 4 days the screen suddenly went weird. The phone itself functions perfectly but can barely read anything on the screen. It appears to purely be a screen malfunction - any help or should I just take it to be repaired?

I doubt it can be repaired...
Once it is wet and not dried properly - putting in a bag of rice for at least 4-5 days - it is damaged.

I wouldn't bother repairing it. Better to just get a new one.

Ouch ok thanks!
